Hi Kerry
Thanks for comments...When your shooting into the sun (contra jour) its always a bit off trade off with lost contrast, lens flare and blown highlights particularly when shooting a long exposure as this is. Personally i dont mind a small section of blown high light if you shooting into the sun (as here) its when you have large patches of white it starts to look strange for me.
Low light long expos into the sun are a trade off and an arm wrestle in processing....this image took some getting sorted that's for sure.
Regards Shaun
